Further inland, the repressive military regime plans to dam one of Asia’s purest rivers and allows gold and gem mines to tear up hillsides and pollute groundwater for quick cash.

Myanmar has become notorious in the region for ignoring international and its own environmental laws in a single-minded effort to make the money that environmentalists say helps keep the regime in power.

“They may have laws on the books, but they mean extremely little,” said Sean Turnell, an expert on the Myanmar economy with Macquarie University in Sydney, Australia. “I would say environmental considerations mean zero to them. It wouldn’t even enter their heads.”

After decades of self-imposed isolation, the junta in the late 1980s began courting foreign investors with offers of stakes in gem mines, forest tracts and hydroelectric projects.

Foreign investment allowed the regime to double its military to 400,000 soldiers while offering neighbors such as China and Thailand access to cheap raw materials and energy to feed their growing economies.

A Myanmar government spokesman did not respond to a request for comment on its environmental record. Chinese government officials could not be reached for comment, and Thailand denied its investment in Myanmar contributes to the country’s environmental destruction.

Hardest hit in the rush to develop the country formerly named Burma have been its rivers and forests, environmentalists say.

Over the past decade, they say, two dozen dams have either been built or are scheduled to be built, mostly with the help of Chinese and Thai firms.

Environmentalists accuse the government of uprooting tens of thousands of villagers to make way for the dams to provide electricity, mostly to Thailand and China.

Among the planned dams are at least five on the Salween, which rises in Tibet and is considered one of Southeast Asia’s last untamed rivers. A first dam is also planned on the Irrawaddy, which activists fear will result in the forced relocation of 10,000 villagers and the decimation of its shoreside fishing communities.

“This region is one of the world’s biodiversity hot spots,” said Naw La of the Kachin Development Networking Group, a coalition of environmental groups watching Myanmar. “If this dam is built on the Irrawaddy, the fish populations will decrease. A lot of people will be suffering because their livelihoods will disappear.”

Along Myanmar’s border with China, illegally felled timber is transported to China, according to the Britain-based group Global Witness. From there, it becomes flooring and furniture for European and American homes.

Global Witness said most of the logging takes place in an area described as “very possibly the most biodiverse, rich, temperate area on earth,” home to red pandas, leopards and tigers.

About 95 percent of Myanmar’s total timber exports to China are illegal, Global Witness said, costing its treasury $250 million a year. Much of the profits go to Chinese firms as well as regional military commanders and ethnic guerrilla groups, it said.

The borders along China and Thailand also are host to massive, unregulated markets that sell everything from illicit gems to animal parts.

At the Tachileik market on the Thai border and Mong La market on the Chinese border, vendors openly sell tiger and leopard skins, bear paws, ivory and live turtles.

The markets are filled with Western tourists looking for souvenirs and Asia businessmen supplying traditional medicine and food markets in China and other Asian countries, activists said.
